Brother mfc-410cn colour cartridge problem
There may be three problems here.
1.Not doubting your skills for one minute, nor wishing to offend you in any way, but did you remove the protection strip off of the Magenta ink cartridge? Sometimes we forget to do that.
2.Once a new ink catridge is installed, it's best to go to the Brother diagnostic tools section, and run a test. Sometimes an error code is kept, (Ink cartridge is empty), and the diagnostic tool checks this out. It then clears the error code, and 'recognizes' the new ink cartridge.
3.Ink may have dried, for the tiny little holes for the magenta ink cartridge, where it attaches to the body of the printer. Just this one ink cartridge. Suggest you don a pair of rubber dishwashing gloves. MFC-410cn -> Unplugged <- from the surge protector, use a clean, lint free, warm water, damp cloth, and wipe the holes for the ink cartridge, where it lines up with the printer body. This will be where you see that copper metal strip. (Or perhaps it's brass)
To clarify, you are cleaning the printer body. The area where the ink cartridge goes, and the metal strip. The ink passes from the ink cartridge, and goes through holes in the body of the printer. The metal strip is where these holes are located. Allow this area to dry. You may want to use a hair dryer set on low heat to speed the drying process up. Constantly move the hair dryer back and forth. Keep it about a finger length away.
Once you are satisfied this are is dry, reinsert the magenta ink cartridge. Plug the printer back into power. Advise waiting one minute, then turn the printer on.
Use the Brother diagnostic tool.
Should you not be able to find the Brother diagnostic tool, I suggest you go to Start>Hover your mouse cursor on All Programs>Go over to Brother>MFC-410cn>and to the Help section. The Help section, will tell you how to open the diagnostic tool.
